본 연구는 가지산의 관속식물상을 밝히고 주요 식물들의 분포를 조사하였다. 2006년 3월부터 10월, 2009년 3월부터 10월까지 총 12회에 걸쳐 수행되었다. 그 결과 관속식물은 106과 314속 503종 6아종 56변종 8품종으로 총 573분류군이 확인되었다. 그 중 산림청 지정 희귀식물은 10분류군, 한국 고유종은 20분류군이 조사되었다. 또한 환경부 지정 멸종위기야생식물은 3분류군, 식물구계학적 특정식물종은 64분류군, 국외반출 승인대상 식물에는 23분류군이 조사되었다. 한편 귀화식물은 22분류군으로 확인되었으며, 귀화율은 3.8%로 나타났다. 조사된 573분류군의 유용도는 식용이 217분류군(37.8%), 약용 181분류군(31.5%), 목초용 91분류군(15.8%), 관상용 86분류군(15%), 목재용 19분류군(3.3%), 섬유용 11분류군(1.9%) 그리고 공업용이 7분류군(1.2%)으로 나타났다.
This study was carried out to investigate the flora of Mt. Gaji(Gyeongsang nam-do). The vascular plants which are collected in 12 times(from May to Oct. 2006 and Mar. to Oct. 2009) were identified as 573 taxa in total, including 106 families, 314 genera, 503 species, 6 subspecies, 56 varieties, 8 forms. There were many useful plants such as 20 taxa of Korean endemics and 10 taxa of specially designated plants which were determined by the Korea Forest Service. The designated in endangered plants by the Ministry of Environment, which should be protected by the wildlife protection law, were identified as 3 taxa and 64 taxa of specially designated floristic regional indicator plants by the Ministry of Environment. Based on the list of approved for delivering overseas of plants, 23 taxa were recorded in the investigated area. The naturalized plants were identified as 22 taxa, and their naturalization ratio were found to be 3.8% respectively. The 573 taxa listed consists of 217 taxa(37.8%) of edible plants, 181 taxa(31.5%) of medicinal plants, 91 taxa(15.8%) of pasture plants, 86 taxa(15%) of ornamental plants, 19 taxa(3.3%) of timber plants, 11 taxa(1.9%) of fiber plants and 7 taxa(1.2%) of industrial plants.
